Setting up your Windows Wallpaper


Introduction

Randwall uses mathematical equations to create its own unique wallpapers at random, saving space in your hard-drive. It creates new desktop backgrounds every time you launch Windows and at user-configurable intervals. The program uses mathematical equations to create its own unique graphics at random from several different internal image families. Use its setup program to determine the dimensions of each tile it generates, as well as the number of colors it uses. RandWall also has a Timer feature so you can change the background automatically in hours, minutes or seconds. You are able to set as wallpaper, save the bitmap and copy the RandWall's bitmaps to clipboard. There are several ways you can change the behavior of RandWall. The wallpaper sample area lets you preview the bitmaps that will be used

as your desktop wallpaper. You may select whether you want to automatically change the

current wallpaper every time the program is started (usually at computer start-up time)

or set the amount of time between wallpaper changes. With RandWall you can stretch the wallpaper on your desktop so that it fills the entire screen. If you don’t have Microsoft Plus installed on your computer, you should check this option to let RandWall stretch the bitmaps to desktop size.


Features

RandWall uses a Control Panel to customize different aspects of the program (change the wallpaper, the bitmap size and the number of colors) to suit your computer and your preferences.

RandWall is a wallpaper randomizer for Windows which has the following features:

Setting up your Windows wallpaper.

As the Control Panel dialog states, configuring RandWall is a 6 step process:

Setp 1: Select height and width.

Setp 2: Select the number of colors.

Setp 3: Select the method of operation.

Randwall by defaul changes the wallpaper when it starts. You can disable it by unselecting the corresponding checkbox.

Step 4: Select the interval.

RandWall is a wallpaper randomizer. Therefore it is expected that you state how often you want the Windows wallpaper to change. You may precisely select the interval between wallpaper changes.

Step 5: Select Desktop settings.

Windows uses two different ways of drawing bitmaps when it uses them as the desktop wallpaper: tiled or centered.

To cover your entire sreen with a small wallpaper image, click “Tile.”

To center a wallpaper image, click “Center.”

In addition, RandWall can be instructed to stretch bitmaps.

Note that Microsoft Plus also has an option to stretch wallpaper so this setting is of interest of users who do not have Microsoft Plus installed.

Setp 6: Press “Set As wallpaper” button.
